Background: Achalasia cardia, not an uncommon disease, is diagnosed based on a good history, upper endoscopy, barium swallow, and standard esophageal manometry, is often diagnosed late and best care is delayed.
Materials and Methods: Complete records of treatment naïve patients with achalasia from 1st January 2000 till 20th November 2004 were reviewed.
Results: A total of 42 patients, with average presenting age at 45±17 (range 19-83) years with 15 males:27 females with 22 Malays:15 Chinese:5 Indians, were analysis. Compared to our upper endoscopy attendees, there is a trend towards a younger age group (p>0.05) but clearly demonstrating a female preponderance (p<0.005) and towards the Malays but sparing the Indians (p< 0.05). The classical symptom of dysphagia was noted in all cases (100%). Regurgitation in 37 patients (88%), heartburn in 15 patients (36%), weight loss in 10 patients, nocturnal cough in 16 patient, retro-sternal chest discomfort in 2 patients and hemetemesis in 2 patient. One patient presented with aspiration pneumonia and another had concomitant active pulmonary tuberculosis and 9 had concomitant constipation (21%). The duration of illness before diagnosis was 66±90 (range 3-360) months and their presenting weight was 52±12 (range 33-82) kg. Barium swallow examination confidently diagnosed achalasia in 28 patients (67 %). The remaining was marked as dysmotility disorder (7 cases), possible carcinoma of the esophagus (in 2 patients) and dysmotility with possible achalasia (in 5 patients). Ten had mega-esophagus and two had epiphrenic diverticulum with no pseudo-achalasia. Standard esophageal manometry, performed in 39 cases, all demonstrated aperistalsis with one vigorous achalasia. The manometric assembly failed to pass through the
sphincter in 14 cases (36%), includes 8 patients with mega-esophagus, and LES assessment was not possible. Four cases demonstrated normal LES pressure but demonstrated incomplete relaxation (normotensive achalasia). Dilatation was performed with a 30 mm Rigiflex pneumatic dilator under fluoroscopy at 7psi for 3-30 seconds after loss of waist in 40 patients without complications and excellent symptomatic relief with 3-12 months post procedural weight gain of 7±5 (range: 0-19) kg. Six patients required a second dilatation and another required two further dilatation. The pneumatic dilatations durability during this short study was excellent at 29±11 (range 8-48) months. Similar efficacy and safety profile was noted in patients with mega-esophagus.
Conclusion: Barium swallow (especially in advanced disease) and manometry (especially in early disease) serve as essential tools for the diagnosis of achalasia and they complement each other. We report two patients presenting with hemetemesis. We obtained excellent results with pneumatic dilatation without any
complications and this extends to advanced cases of achalasia with mega-esophagus.
